BACKGROUND The urea breath test (UBT) with a microdose of [14C] is a non-invasive and simple method for the assessment of gastric infection by Helicobacter pylori. The aim of this study was to compare the [14C]UBT with invasive methods widely used for assessment of H. pylori gastric infection, including histology with hematoxylin-eosin staining, the gastric(More)
BACKGROUND Nodular thyroid disease is a very common disorder with a low frequency of malignancy. The most accurate diagnostic test is fine needle aspiration biopsy (FNAB) of nodules with cytological analysis of the sample.

BACKGROUND Follicular carcinomas account for 15% of thyroid malignant tumors. The differential diagnosis between adenoma and minimally invasive follicular carcinoma is difficult and lacks reproducibility especially in frozen sections. As the diagnosis depends on finding foci of capsular invasion, multiple sections must be examined. Numerous(More)
OBJECTIVES To compare the expression of nerve growth factor (NGF) and its high-affinity receptor trkA in normal ovaries and in epithelial ovarian carcinomas. Given NGF acts as an angiogenic factor through a vascular endothelial growth factor (VEGF)-mediated mechanism in several types of tissues, we examined whether NGF regulates the expression of VEGF(More)
We report a 78 year old male with prostatism, that was subjected to a prostate biopsy. The pathological study showed a microvascular lymphocytic infiltration. Four months later, the patients presented with reduced alertness, cough, dyspnea, fever and elevation of lactic dehydrogenase and erythrocyte sedimentation rate.

The presence of cancer in a hernia sac is uncommon. The tumor can involve the hernia sac, the herniated mass or be external to the hernia sac. We report two cases with this condition. A 68 years old male was operated of a right inguinal hernia. During surgery, several white nodules were noted in the internal side of hernia sac. The same lesions were present(More)
